It was narrated from Ishaq bin ‘Abdullah bin Ja’far that his father said: “The Messenger of Allah (ﷺ) said: ‘Urge your dying ones to say: “La ilaha illallahul-Halimul-Karim, Subhan-Allahi Rabbil-‘Arshil-‘Azim, Al-Hamdu Lillahi Rabbil-‘alamin (None has the right to be worshipped but Allah, the Forbearing, the Most Kind. Glory is to Allah, Lord of the magnificent Throne; praise is to Allah, the Lord of the worlds).’” They said: ‘O Messenger of Allah, what about those who are alive?’ He said: ‘Even better, even better.’”
